    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

David Greenberg

Hi, my name is David Greenberg and I'm the Director of Technology for the Mohawk Trail Regional School District in western Massachusetts. I've been helping teachers use computers in their classrooms for the last 10 years or so. I have a Masters degree in Education and before I worked in schools, I was a computer consultant and a hardware and software designer.

Actually, that's sort of where my interest in MILAGRO comes from. I own a small company called PAX Analytics that manufactures a 'plug and play' portable air quality monitoring system, used by a number of schools around the country, so when I got a chance to participate in MILAGRO, I just couldn't pass it up.

I will be working with Paul Voss, who is a scientist at Smith College in Northampton, Massachusetts. Paul has developed this very cool balloon that can be controlled from the Internet. It carries several sensors and we will use it to see where the air pollution for which, unfortunately, Mexico City is famous, goes after it leaves the city.

I'm going to be posting to the Windows to the Universe web site and if I'm able to, I will try to upload some video footage of the exciting things we're doing in Mexico. Stay tuned!
